METHANOL SYNTHESIS PLANT (OPTIONS) Russian patent published in 2021 - IPC C07C29/151 C01B3/32 B01D3/00 B01D53/26 C02F1/00 C07C31/04 

FIELD: gas industry.

SUBSTANCE: present invention relates to options of a methanol synthesis plant. One of options of the plant includes a unit for obtaining synthesis gas with a device for its drying, lines for supplying a raw material mixture, fuel and part of waste gas as fuel, a unit for obtaining methanol with a catalytic reactor equipped with a refrigerant input line and a methanol release device equipped with lines for outputting raw methanol and outputting waste gas. The line for supplying a raw material mixture is connected to the line for outputting part of waste gas from the methanol release device, as well as lines for supplying hydrocarbon raw materials from prepared water, devices for drying synthesis gas and for releasing methanol are equipped with lines for inputting the first and the second parts of a raw material mixture as the refrigerant and lines for outputting partially heated the first and the second parts of a raw material mixture that are connected with the formation of a line for supplying refrigerant to the catalytic reactor of methanol obtaining equipped with a line for supplying a heated raw material mixture to the unit for obtaining synthesis gas that is equipped with a line for supplying the residual part of waste gas as fuel from the methanol release device and a line for supplying balance fuel amount, in addition, the plant is equipped with a water preparation unit equipped with lines for supplying water condensate from the device for drying synthesis gas, inputting process water and supplying prepared water to the line for supplying a raw material mixture.

EFFECT: reduction in energy consumption.
